<2> The setting range is determined by parameter A1-02, Control Method Selection.
<3> Default setting is dependent on parameters A1-02, Control Method Selection, and o2-04, Drive Model Selection.
<4> Default setting is dependent on parameter o2-04, Drive Model Selection.
<5> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.

YASKAWA ELECTRIC TOEP C710616 41B YASKAWA AC Drive - A1000 Quick Start Guide
Description
Sets the number of pulses per revolution for the PG being used (pulse generator
or encoder).
Sets the offset between encoder offset and the rotor magnetic axis.
Description
Sets the frequency of the test signal used during Inertia Tuning and ASR Gain
Auto-Tuning. Reduce this value if the inertia is large or if a fault occurs.
Sets the amplitude of the test signal used during Inertia and ASR Gain Auto-
Tuning. Reduce this value if the inertia is too large or if a fault occurs.
Sets the motor inertia. Default setting is the inertia of a Yaskawa motor.
Sets the response frequency of the mechanical system connected to the motor.
Oscillation may result if set too high.
